POUNClNG-HEAD FOR HAT- POUNCING MACHINES.

SPECIFICATION forming part of Letters Patent No. 495,491, dated April18, 1893. Application filed March 2, 1892. Serial No. 423.619- (Nomodel.)

To ztZZ whom it may concern.-

Be it known that 1, JOHN B. HOWE, a citizen of the United States,residing at Danbury, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements inPouncing-Heads for Hat- Pouncing Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which itappertains to make and use the same. a

This invention relates to certain new and useful improvements inpouncing heads for hat-pouncing machines, such for instance as is shownin my patent No. 480,098, dated August 2, 1892. Pouncing heads adaptedto contain an abrasive grinding device, such for instance as a sheet ofsand-paper are not broadly new, but in using them it is necessary a forthe operator to exercise considerable care in keeping the hat free fromthe dust which results from the action of the sandpaper on the hat, asthis, ifallowed to remain, will be rubbed or ground into the feltedsurface, to

the injury of the latter.

It is the object of my present invention to combine with the pouncerhead a brush, which, as fast as the surface is ground off or pouncedwill remove therefrom the dust and cuttings. I

It is also an object of my invention to provide a pouncer head of noveland convenient construction, and to provide means for the, readyinsertion and release of the sandpaper and with these ends in view myinvention consists in the construction and combination of elementshereinafter fully and in detail explained and then recited in theclaims.

In order that those skilled in the art to which my invention appertainsmay fully understand its construction and method of operation, I willdescribe the same in detail, reference being had to the accompanyingdrawings, forming a part of this specification, and in which,

Figure 1, is a side elevation; Fig. 2, a longitudinal vertical sectionFig. 3, a detail elevation of the collars shownat the right of Fig. 2;Fig. 4, a detail vertical section at right angles to Fig. 2; Fig. 5, adetail elevation; Fig. 6, a detail bottom plan showing the graspingfingers; Fig. 7, a plan View of the pad-sup .venient part of themachine.

porting plate, and, Fig. 8,a perspective showing the grasping deviceseparate from the other parts.

The same numerals denote the same parts in all the figures.

The support or base of the pouncer head is denoted by the numeral 1, andis mounted upon the end of a suitable pouncer arm 2, shown as broken offat the left of Figs. 1 and 2. Opposite to the pouncer arm is located ahandle 3 whereby the base and its attached parts may be moved relativeto the hat to be operated upon.

The base has formed therein a'vertical bearing, see Fig. 2, and in thisis seated and adapted to revolve a tubular short shaft 4 held in placebya screw-plate 6, shown in bottom plan view at Fig. 6, and this has adovetailed slide-way 7 to which by a similar dovetail 8, a plate 9 issecured, see also Fig. 5. To this plate 9 is attached, as by screws, apad or cushion 10 made up of one or more thicknesses of rubber, leatheror the like. The plate 6 is channeled or recessed across its lower face,see Figs. 1 and 4, for the reception of a grasping device consisting ofa flat sheet metal strip 11 having its ends downwardly and inwardly bentto form fingers 12. This strip has a small central hub 13 and this isconnected to a screw-threaded driving shaft 14 which extends downwardthrough the hollow shaft 4, as seen at Figs. 2 and 4, and whose upperend is connected to a flexible shaft 32. This flexible shaft is drivenfrom any con- As the strip having the grasping fingers lies in therecess of the plate 6, the shaft 14 in carrying the strip necessarilycarries the plate and its connections. Upon theshaft 14 is a collar 16between which and the top of the shaft 4 is interposed a shortspiralspring 17 whose action is normally to hold the several parts inthe position in which they are shown at Fig. 4. If, however, the shaftbe pushed downward against the action of the spring thegrasping fingerswill be disengaged and carried away from the flanged face of the cushionor pad, as appears at Fig. 5. For effecting this disengagement a lever18 is provided having an opening through which the shaft 14 freelyextends. crumed, as at 19, 011 an upright bolt 20, which latter ismounted on the base 1. Beneath the lever and around the bolt is a spiralspring 21 whose function it is to normally retain the lever 18 out ofengagement with the collar 16 on the shaft 14. The parts hereinbeforedescribed make up a complete and operative pouncer and constitute onebranch of my invention.

Between the hub in which the shaft 14 is mounted and the handle 3, is anaxle or hearing denoted by 22. Upon this is rotatably mounted a bearingcollar 23 screw-threaded on its outer surface and is provided with aflange 24. Upon this bearing collar is a wheel or roll 25 of rubber,leather or other material, and its periphery engages against an annularinclined surface 26 formed upon the top of the plate 6. The wheelor disk25 is supported upon one side of the flange 24 and is crowded firmlyagainst the latter by means of a screwthreaded flanged collar 26. Uponthis lastnamed part is fitted the hub of a brush 27, whose interior ishollowed out, as shown at Fig. 2, and whichis secured to the base by ascrew-threaded abutment collar 28 also running on the screw-threadedsurface of the part 23. Beyond this collar a ring 29 surrounds the-bearing and between this and the handle is interposed a spring 30 whosefunction it is to press the brush, the friction wheel and the otherattached parts away from the handle, and to keep the periphery of thefriction disk 25in firm and constant contact with the surface 26. p

In the operation of my invention the sandpaper, which is numbered 31 atFig. 4, is inserted by first throwing down the grasping jaws or fingersto the position shown at Fig. 5 by means of the handle 18, and then,after placing the sandpaper within the field of action of the fingers,permitting the parts to be returned to their normal position by theaction of the spring 17. The shaft 14, when the machine is in operation,is driven at a high rate of speed from the flexible shaft 32 carryingwith it the sandpaper, and it is then passed over the surface of the hateither by hand, through the medium of the handle 3, or by means of someautomatic mechanism, such as is shown in my Letters Patt'ent heretoforereferred to. As the revolving head passes over the hat it grinds off theprojecting fibers of the felt in the form of dust, as has already beenexplained. The brush 27, however, is driven by the frictional connectionheretofore described, and performs toward the hat, simultaneously withthe grinding, a cleansing orsweeping function whereby the dust isremoved as fast as made and is not therefore worked into the felt.

I have shown what I believe to be the best means, all things considered,of connecting the brush with the pouncer head, but I do not wish to beconfined to the specific construction herein shown and described, sinceit may be widely varied and altered without departing from theessentials of my invention, which I deem commensurate in scope with theterms of the claims here following.

I claim- 1. In a machine of the character described, the combinationwith a revoluble pouncing head, of a brush borne upon the same frame assaid pouncing head, and a driving connection interposed between saidbrush and pouncing head whereby the former is driven simultaneously withand by means of the latter, substantially as described.

2. In a machine of the character described, the combination with therevoluble pouncer head, of the brush having its axis at right angles tothe axis of the pouncer head, and frictional driving gear interposedbetween the brush and head, whereby the former is driven from thelatter, substantially as described.

3. In a machine of the character described, the combination with therevoluble pouncer head provided on its top with a friction ring orsurface,- of a brush mounted adjacent to said pouncer head, and afriction disk connected to the brush and engaging the friction surfaceon the head, substantially as and for the purpose set forth.

4. The combination with the shaft 14 provided with the grasping jaws orfingers, of the head connected to and carried by said shaft, and aspring interposed between and having suitable connection with saidshaftand head, and means as described for moving said jaws or fingersrelative to the head.

5. The combination with the revoluble body having a handle for itsmanipulation, of the vertical shaft provided with suitable graspingjaws, the pad with which said grasping jaws co-operate, a springengaging the shaft 14 and adapted to hold the grasping surfaces normallyin their clamped position, and a lever having engagement with the shaft14 whereby the temporary disengagement of the clamping devices may beeffected.

6. In a device of the character described, the combination of the plates6 and 9 having a dovetailed engagement, the pads secured to thelowermost of said plates, and the shaft 14 provided with grasping jawsand movable relative to said plates, the whole constructed and adaptedto operate substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
